Abstract
A combined laser beam shutter and beam 'on-off' indicator is disclosed. A rotatable shutter pin is mounted in a beam interrupting positon with the shutter having an aperture thereon which, when the pin is rotated to the proper position, permits passage of the light therethrough. The shutter pin is adapted, when in closed position, to reflect visible light caused by the laser to a position for observation thereby indicating that the beam is 'on'.
